Government officials and bodies - such as the National Highway Traffic Safety Administration (NHTSA) - are receiving more letters and e-mail from drivers in the complaining about the problem of headlamp glare, according to the Los Angeles Times. The problem is being linked to growing numbers of sport utility vehicles - with relatively high-mounted headlamps - on the roads. According to the Times, NHTSA has received - after inviting consumer feedback - more than 1,700 letters and e-mails in five months. It is described as "one of the largest public responses to an NHTSA request in years." According to the report, the headlight glare problem attracted more complaints than such topics as airbags and window tinting. Carmakers and vehicle safety experts have already suggested that lawmakers lower the mounting height of headlights from the current maximum of 54 inches off the ground - a limit that has been in place since 1968, according to the Times. The report adds that the Alliance of Automotive Manufacturers has recommended lowering it to 47 inches, while the SAE has suggested bring it down even further, to about 39 inches.
